This year, my “powered by solar” reads as 42% (similar for previous years), but I actually overproduce. Shouldn’t the percentage be >100% in this case? The “grid” basically acts just as storage. (It is actually better than that, because I am on a TOU plan and feed the grid at the high day rate and get it back at night at a lower rate)
Obviously there are many ways to define that percentage number. I am curious what formula is used to get 42% from the values shown. Wouldn’t it be more useful to calculate (or alt least also display) net over/under-production.
